IMPROVEMENT IN LOCKS OF DOUBLE-BARRELED GUNS.

Specification forming partof Letters Patent No. 19,121, dated January19, 1858.

ble-Barreled Guns by Means of a Single Trigger; and I do hereby declarethat the following is a full and exact description, to wit:

The nature of my invention consists in placing upon the ordinarytrigger-plate of a gunlock but one trigger on adouble-barreled gun,which, when pulled, will fire one or both barrels, as may be desired.

To enable others skilled in the art to make and use my invention, I willproceed to describe the construction and operation of the same,reference being had to the accompanying drawings, making part of thisspecification, in which- Figure l is a side view; Fig. 2, an end view;Fig. 3, a reversed view of Fig. 2, and Fig. 4 a

perspective view.

My trigger-plate is of the usual form, (see Figs. 1 and 4, a,) with aprojection on each side of the plate, Figs. 1 and 2, b,- from thetrigger 0, Figs. 1 and 4, a similar projection, 6, Figs. 2 and 4. Thereis,a fly-lever, Fig. 4, f, with a concave groove in the back, Figs. 3and 4, g, and with two projections to correspond with e on the triggerand b on the plate, all of which, when put together, forms a substantialand durable hinge. The use of the back with the concave groove in thefly-lever is to work against both of the edges of the lock, which itcomes in contact with when the trigger is pulled, so as to throw one orboth at the same time, at the option of the user,which ob-' Viates theliability of pulling the wrong trigger,which is often done in the hurryof firing, as in all cases each barrel is discharged by having itsrespective lock cooked and fired by pulling the single trigger. It Wi llthus be seen that a double-barreled gun need to have but one trigger,which is a great advantage over the common method of making them.

What I claim as my invention, and desire to secure by Letters Patent, is

- Placing a projection upon the trigger-plate, a corresponding one onthe trigger and fiylever, with a projection of a similar kind and aconcave groove substantially arranged so as to form a permanent hingefor the uses and purposes set forth in the specification.
